Is Sage Jupyter kernel pipe-based?
(Jupyter uses zeromq, which can do inproc communication, and as far as I
know some kernels do this)

he wanted to use Python3 modules from system's Python3.
Without extreme care, and quite possibly source code changes in Sage,
this won't work.

Incidentally this brings up the question on how one should deal with
outdated (as they had to by Python2-compatible)
Sage's iPython and Jupyter.

Re: [sage-support] Re: sage building with python3

[John H Palmieri]

If you want to build Sage for use with Python 3, you should do

$ make distclean
$ ./configure --with-python=3
$ make

Where does this fail for you?

More: when I pip install prompt_toolkit, is installing prompt-toolkit 
1.0.15. But ipython says:

Installing collected packages: prompt-toolkit
  Found existing installation: prompt-toolkit 1.0.15
Uninstalling prompt-toolkit-1.0.15:
  Successfully uninstalled prompt-toolkit-1.0.15

install ipython and prompt_toolkit

Re: [sage-support] Re: sage building with python3

[Dima Pasechnik]

Well, it is not clear what you are trying to do. Yes, if you want to use
more recent than used in Sage (for compatibility with Python2 reasons)
packages, then various things need to be adjusted. It has to be done in a
systematic way.

Another error:

jupyter-console 6.0.0 has requirement prompt-toolkit<2.1.0,>=2.0.0, but

ipython 7.9.0 has requirement prompt-toolkit<2.1.0,>=2.0.0, but you'll have

 Hi Dima,

 IIRC, that's not true for Sage's py-3 version. Namely, if one opens a
 sage-with-py-3 shell, then "python" still means "python2". So, if you
 really want Sage-with-py-3's Python installation, you should either do
 "sage -python" or (in a Sage shell) "python3". And I think the same
 holds for pip.

 Best regards,
 Simon

[sage-support] Re: sage building with python3

[Александр Ватузов]

"./sage -pip install cython" installs cython for python3: Requirement 
already satisfied: cython in ./local/lib/python3.7/site-packages (0.29.14); 
and
"Requirement already satisfied: gmpy2 in 
./local/lib/python3.7/site-packages (2.0.8)"

So I think that, may be, cython need gmpy2 installed in other way? I still 
have na error:

[sagelib-8.9] cimport gmpy2
[sagelib-8.9]^
[sagelib-8.9] 
[sagelib-8.9] 
[sagelib-8.9] sage/rings/complex_double.pyx:110:8: 'gmpy2.pxd' not found
